を特徴とする人工透析用脈波検出装置。[Claims for Utility Model Registration] When blood flowing in an artery of a living body is taken out to the outside via a blood circulation circuit connected to the artery for dialysis, pulse waves generated in synchronization with the heartbeat of the living body are collected. An artificial dialysis pulse wave detection device used for detection, which is installed in a part of the blood circulation circuit and outputs a pressure signal representing the pressure in the blood circulation circuit that changes with the pulsation of the artery. A pulse wave detection device for artificial dialysis, characterized by including a pressure sensor.
